Dust extraction,
mobile and stationary.

Without extraction, blasting is neither reasonable nor permitted. We build the system that carries the dust away where it is created — on site as well as in production.

Two designs
Site and works

Where the system stands
decides its design.

  1. Mobile dust extraction unit on support legs, control cabinet with emergency stop open

    Mobile

    Site dust extraction

    Mobile filter units for use on location. They hold the enclosed area under negative pressure, extract the dust and separate it through continuously cleaned filters.

    • In several sizes
    • Sized to the enclosed volume, the required air volume flow and the air change rate
    • Can be configured for hazardous substances — asbestos, lead, PCB, PAH
  2. Stationary filter unit with centrifugal fan, ducting and dust discharge into containers, next to a blast media reclamation unit in the hall

    Stationary

    Dust extraction in production

    Permanently installed systems for blast rooms, wheel blast machines and machining stations. They are planned together with the building — ducting, capture elements and filter capacity follow from actual operation, not from a catalogue.

    • Filter unit cleaned down during operation
    • Dust discharge into drum, big bag or container
    • Exhaust air routed indoors or outside
    • Separation up to dust class H to EN 60335-2-69
  3. Discharge hopper of a mobile dust extraction unit with flexible ducting to the big-bag station

    Discharge

    Where the dust goes

    The separated dust has to leave the system in a controlled way — with hazardous substances, dust-tight and without anyone decanting it in the open. The discharge is therefore sized with the same care as the filter itself.

    • Drum discharge with a connection under the hopper
    • Big bag station for larger quantities
    • Dust-tight design for dust containing hazardous substances
hazardous substances
Negative pressure and filter stages

Asbestos, lead,
PCB, PAH.

When removing coatings that contain hazardous substances, success is decided not by the blasting but by the air management. Every one of our systems — mobile as well as stationary — can be configured for it.

The enclosure is held under negative pressure. Air flows in under control and leaves the area only through the filter.

That keeps the hazardous substance inside the system even if the enclosure has a leak — the direction of flow always points inwards. That is the difference between an extraction unit and a system you are allowed to remove asbestos with.

  • Asbestos

    Sprayed asbestos, asbestos cement, asbestos-containing coatings. The system is configured to the requirements for demolition work involving asbestos.

  • Lead

    Red lead and lead-bearing old paint of the kind found on bridges, masts and hydraulic steel structures from several decades back.

  • PCB

    Polychlorinated biphenyls from joint sealants, paints and coatings of the construction period between the nineteen-fifties and nineteen-eighties.

  • PAH

    Polycyclic aromatic hydrocarbons, for example from tar and bitumen coatings on tanks and pipework.

Which protective measures apply in an individual case is determined by the competent authority and the survey of the structure. We build the system that meets those requirements — the assessment itself is not our task.

Have the air volume sized

Tell us the dimensions of the enclosure or hall — we will calculate the extraction capacity needed.
